Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a structure of a shipborne automatic water quality sampler, including: a bracket 1, a winding roller 2, a motor 3, a first connecting line 4, a sampling cylinder 5, a rubber band 6, a pulley 7, a valve plate 8, a cover plate 9, a connecting rod 10, a pin 11, a spring 12, a float 13, a spring 14, a connecting shaft 15, a second connecting line 16, a rope loop 17, a connecting plate 18, and a locking sleeve 19; A bracket 1 is provided with a winding roller 2 at its top and a first connecting line 4 connected to the outer side of the winding roller 2. A motor 3 is connected to the right end of the winding roller 2 and is fixedly connected to the bracket 1. A sampling cylinder 5 is connected to the bottom end of the first connecting line 4 and a rubber band 6 is connected to the outer side of the sampling cylinder 5. A cover plate 9 is provided at the top of the sampling cylinder 5 and a valve plate 8 is provided inside the sampling cylinder 5. A connecting rod 10 is connected to the middle of the top of the valve plate 8 and a rubber band 6 is connected to the outer side of the top of the valve plate 8. A pin 11 is provided at the top of the cover plate 9 and a spring 12 is provided outside the pin 11. A float 13 is provided at its bottom with a connecting shaft 15, and a spring 14 is connected to the left end of the connecting shaft 15. A second connecting line 16 is connected to the outside of the connecting shaft 15, and the bottom end of the second connecting line 16 is connected to the outside of the pin 11. A rope loop 17 is provided outside the second connecting line 16, and a connecting plate 18 is connected below the rope loop 17. A locking sleeve 19 is provided outside the connecting plate 18.

[0017] like Figure 1 and Figure 2The top of the sampling cylinder 5 is provided with pulleys 7 at equal angles, and the middle part of the rubber band 6 is located outside the pulleys 7 to facilitate the stretching of the rubber band 6. The valve plate 8 is slidably and sealed to the sampling cylinder 5, and the connecting rod 10 at the top of the valve plate 8 passes through the top of the cover plate 9 to facilitate the sliding of the valve plate 8 by the connecting rod 10. The pin 11 and the cover plate 9 form a sliding structure, and the connecting rod 10 and the cover plate 9 are engaged by the pin 11 to facilitate the fixing of the position of the valve plate 8.

[0018] like Figure 3 and Figure 4 The middle rope sleeve 17 is fixedly connected to the connecting plate 18 in an integrated structure, and the rope sleeve 17 and the second connecting line 16 form a sliding structure, providing conditions for controlling the extension of the second connecting line 16. The rope sleeve 17 is engaged with the bottom of the float 13, and the connecting plate 18 is symmetrically arranged on both sides of the rope sleeve 17 to facilitate limiting the extension of the second connecting line 16. The connecting plate 18 is threadedly connected to the locking sleeve 19, and the individual connecting plates 18 have a trumpet-shaped structure. The rope sleeve 17 is fixedly connected to the second connecting line 16 through the connecting plate 18 and the locking sleeve 19, which facilitates the fixing of the rope sleeve 17.

[0019] Working principle: When using the structure of this shipborne automatic water quality sampler, such as... Figure 4 As shown, the extension of the second connecting line 16 is pre-adjusted according to the water sampling depth. After the extension of the second connecting line 16 is adjusted, the locking sleeve 19 is rotated to squeeze the connecting plate 18, so that the connecting plate 18 clamps the second connecting line 16, thereby fixing the rope loop 17 on the second connecting line 16. like Figure 2 As shown, by pressing the connecting rod 10, the connecting rod 10 causes the valve plate 8 to move down, and the elastic band 6 is pulled to store force. After the connecting rod 10 is pressed down a certain distance, the pin 11 is inserted into the hole in the connecting rod 10 under the compression of the spring 12, and the connecting rod 10 is locked in the cover plate 9, thereby fixing the valve plate 8 in the sampling cylinder 5. like Figure 1 As shown, by starting motor 3, motor 3 drives winding roller 2 to rotate, winding roller 2 releases the first connecting wire 4, causing sampling tube 5 to enter the water under the action of gravity. Simultaneously with the descent of sampling tube 5, pin 11 pulls on the second connecting wire 16, causing the second connecting wire 16 to extend and pull connecting shaft 15 to rotate, causing spring 14 to store power. After sampling tube 5 descends to the designated depth, as... Figure 4 As shown, the loop 17 on the second connecting line 16 engages with the bottom of the float 13, preventing the second connecting line 16 from extending further and causing the float 13 to move downwards under the pull of the sampling tube 5, as shown. Figure 2As shown, this increases the buoyancy of the float 13, causing it to pull the pin 11 through the second connecting line 16 and compress the spring 12, separating the pin 11 from the hole in the connecting rod 10. This causes the valve plate 8 to reset under the action of the rubber band 6, drawing water into the sampling cylinder 5. A one-way valve is provided at the bottom of the sampling cylinder 5 to facilitate water entry. Because the float 13 pulls out the pin 11, the float 13 tends to float on the water surface, similar to the bobber of a fish, making it easier for personnel to judge the water pumping status of the sampling cylinder 5. After the sampling cylinder 5 completes sampling, the motor 3 is started in reverse, causing the motor 3 to drive the winding roller 2 to retract the first connecting line 4, thereby causing the sampling cylinder 5 to move upward. At the same time, the spring 14 drives the connecting shaft 15 to rotate in the opposite direction, retracting the second connecting line 16. This is the entire working process of the structure of the shipborne automatic water quality sampler.
